Juvenile Court Officers’ Perceptions Of Innovation Adoption; What Personal And Contextual Factors Make A Difference In Levels Of Adoption? An Exploratory Mixed-Method Study., Brenda Jean Moran

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This exploratory research examined levels of innovation adoption among Juvenile Court Officers (JCOs) in a Midwestern state. The researcher applied Everett M. Rogers’ Diffusion of Innovation model as the study’s framework. According to Rogers (2003), innovation is “an idea, practice or object that is perceived as new by an individual or other unit of adoption” (p. 475). The study sought to determine the extent that demographic and work-life variables such as gender, office location, caseload, years of service, personality/temperament and employee engagement contributed to levels of innovation adoption by JCOs. This study examined the characteristics of individuals and contexts in …

Effects Of Time Varying Background Noise Conditions On Human Perception And Performance, Andrew H. Hathaway

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

This thesis was designed to study the effects of changing noise conditions on human perception and performance. In two phases, participants were exposed to a number of noise conditions and their performance on an arithmetic task involving short-term memory was monitored and their subjective perception of noise conditions was collected via questionnaires.

In the first phase, participants were tested while being subjected to RC-29(H) and RC-47(RV) conditions created by broadband noise fluctuating on different time intervals, resembling the changing noise conditions potentially found in modern HVAC systems. These intervals varied from two minutes to ten minutes. Results show a significant …

"Hunger Is The Best Sauce": Frontier Food Ways In Laura Ingalls Wilder's Little House Books, Erin E. Pedigo

Department of History: Dissertations, Theses, and Student Research

This thesis examines Laura Ingalls Wilder's Little House book series for the frontier food ways described in it. Studying the series for its food ways edifies a 19th century American frontier of subsistence/companionate families practicing both old and new ways of obtaining food. The character Laura in Wilder's books is an engaging narrator who moves through childhood and adolescence, assuming the role of housewife. An overview of the century's norms about food in America, the strength of domesticity as an ideal, food and race relations, and the frontier as a physical place round out this unexplored area of Little House …

Hardy, Darwin, And The Art Of Moral Husbandry, Owen Roberts-Day

Department of English: Dissertations, Theses, and Student Research

This study of the influence of Charles Darwin on Thomas Hardy's tragic novels centers on two key concepts in the work of Darwin. The first is Darwin's narrative of the evolution of morality, which describes moral decisions as a struggle for survival between various instincts, habits, and customs, both within the individual and within society as a whole. Of particular importance is the role of reason and sympathy in overcoming base and selfish instincts. The second is the idea, introduced in Origin, that the work of scientific breeders represents an act of Conscious Selection, a separate form of evolution …

Investigation Of Commercial Milk Enzyme-Linked Immunosorbent Assay (Elisa) Kits: Specificity And Utility For Residues Of Foods Subjected To Proteolysis During Processing, Katherine O. Ivens

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Analytical methods, such as enzyme-linked immunosorbent assays (ELISA), are used to detect and quantify residues from allergenic sources in food products. However, ELISAs have not been validated for use in foods that have been exposed to proteolysis. This thesis explores the specificities, sensitivities, and capabilities of commercially-available milk ELISA kits for detecting milk residues in cheeses that have undergone varying degrees of proteolysis.

The specificity, accuracy, and consistency of twelve commercially-available milk ELISA kits for individual milk proteins and commonly used milk-derived ingredients, including α-,β-, and κ-casein, β-lactoglobulin, α-lactalbumin, non-fat dry milk, sodium caseinate, and whey protein concentrate were evaluated. …

The Influence Of Regulations On Duck Hunters And Harvest, Matthew T. Haugen

School of Natural Resources: Dissertations, Theses, and Student Research

Although regulations, duck hunters, and duck harvest are interconnected, the relationships among them have not been fully explored. I used U.S. Fish and Wildlife Service’s Parts Collection Survey to examine both duck harvest and duck hunter behaviors with regard to regulations in the Central Flyway. I first examined what factors best explained the daily variation in harvest distribution across the hunting season for mallards (Anas platyrhynchos), dabbling ducks (Anas spp.), and diving ducks (Aythya spp.). Secondly, I examined how hunter behaviors were influenced by harvest regulations. Finally, I documented co-occurrence of duck species in the daily …

Anoxia Tolerance Of Forensically Important Calliphorids, Melissa M. Lein

School of Natural Resources: Dissertations, Theses, and Student Research

Forensically important blow flies, Diptera: Calliphoridae, are among the first organisms to colonize carrion. After eggs hatch, the larvae of most blow fly species feed in an aggregation or “mass.” While in this mass larvae may experience periods of no oxygen (anoxia), little oxygen (hypoxia), or normal oxygen (normoxia), but the tolerance of blow fly larvae to severe hypoxic conditions is not known. I tested the anoxia tolerance of four species of calliphorids (Calliphora vicina, Cochliomyia macellaria, Lucilia sericata, and Phormia regina), using third stage larvae across five temperatures. Experiments were conducted by exposing larvae to pure nitrogen …

Predicting Invasion Risk Of Non-Native Plants Using A Modified I-Rank Assessment, Justin B. Williams

School of Natural Resources: Dissertations, Theses, and Student Research

Biological invasions are a global problem responsible for native species declines worldwide. Understanding the invasion risk from non-native species is important in establishing management goals and making decisions for managing native ecosystems. Useful modeling methods for quantifying or predicting invasion risk should consider research needs, data availability, and operate at an appropriate scale. I evaluated risk assessment methods towards answering a specific research question; which plant species pose the greatest risk of becoming invasive or having the greatest negative impact in Nebraska? I selected the I-Rank assessment method, which consists of 20 questions grouped into four risk categories or Subranks: …

The purpose of this project was to explore the use of quality children’s literature in enhancing science instruction in the third grade curriculum while implementing and helping students meet the English Language Arts Common Core State Standards (ELA CCSS). I researched how using children’s literature in the science curriculum may be beneficial for students. I have created a handbook that third grade teachers can use as …

Theoretical Tailoring Of Perforated Thin Silver Films For Surface Plasmon Resonance Affinity, Renan Gongora

HIM 1990-2015

Metallic films, in conjunction with biochemical-targeted probes, are expected to provide early diagnosis, targeted therapy and non-invasive monitoring for epidemiology applications [1-4]. The resonance wavelength peaks, both plasmonic and Wood-Rayleigh Anomalies (WRAs), in the scattering spectra are affected by the metallic architecture. As of today, much research has been devoted to extinction efficiency in the plasmonic region. However, Wood Rayleigh Anomalies (WRAs) typically occur at wavelengths associated with the periodic distance of the structures. A significant number of papers have already focused on the plasmonic region of the visible spectrum, but a less explored area of research was presented here; …

Social Networking And Users: The Interaction Of Personality And Motivation To Post On Facebook, Theresa Kessler

HIM 1990-2015

Facebook is the reigning king of Social Networking Sites (SNSs). Due to Facebook’s impact on current culture, researchers have been focused on how it interacts with its members on a variety of issues including well-being, personal identity, personality type, and motivation. While the topics of personality type and motivation have been investigated separately, their possible relationship has not been examined until now. Participants consisted of 415 students from the University of Central Florida were surveyed with an International Personality Item Pool (IPIP), a Facebook Intensity Survey, and a Facebook Motivation Scale. Results showed that the personality traits of agreeableness, conscientiousness, …

Survey Of Comparative Human And Non-Human Osteology: Common Florida Species, Jennifer Dewey

HIM 1990-2015

Forensic anthropologists are tasked with the responsibility of identifying human remains in a forensic context. This includes differentiating between human and non-human osteological remains, and further determining a species-specific identification when presented with nonhuman material. Previous research has provided manuals that are typically limited to one class of animal and includes either photographs or descriptions of cranial or post-cranial skeletal elements. Further, the available resources generally cover a limited number of species from Florida#s diverse habitat. Therefore, the intent of this thesis was to compile a comprehensive comparative osteological guide of local Florida species that addressed both cranial and postcranial …

Boy Student/Girl Student: Exploring Early Childhood Teacher Perceptions Of Gender And Their Influence On Children's Learning, Elizabeth Oliver

HIM 1990-2015

Brain development in children has always been fascinating to me; it was the reason I chose to major in Early Childhood Education. I have often wondered how the expectations and behavior of parents and teachers affect young children academically. Specifically, how do early gender messages from adults, peers, and the popular media have a powerful impact on the development of young brains? The professional responsibility of all educators is to help every child reach their full potential. This thesis explored the potential impact early childhood educators have in developing and reinforcing stereotypes that can affect children academically by surveying teachers …

At The Frontlines Of The Kulturkampf: Social Policy Positions Of Undergraduate Students At A Large University In The Southeastern United States, Julio Montanez

HIM 1990-2015

Social policy concerns groups. Specifically, social policies have been implemented as a means to affect the well-being of sexual and gender minorities, including areas such as health, employment, violence, and many others. Undergraduate student opinions on such policies are an understudied area of survey research. Possible correlates of support for such policy areas include, but are not limited to, sexual prejudice, attributions, increased contact with the minority group, gender, Para-social contact, and many others. This research administered a 55-item survey to undergraduate students at the University of Central Florida. With a sample of 210 individuals, this study aimed to answer …

The Effects Of Stress On Distance Perception, Monica Rosen

HIM 1990-2015

Although there has been a great deal of research on binocular distance perception (Foley, 1980; Gogel, 1977), a number of questions remain unexplored. One such question involves how our ability to perceive distances is influenced by fitness and stress (internal and external). Previous research has shown that kinesthetic stress (via backpack weight) influences a person’s ability to accurately guess distances (Proffitt, Bhalla, Gossweiler, & Midgett, 2003). This research did not only attempt to replicate previous work, but also extend it by exploring potential interactions between fitness level and mental stress on distance perception, a combination that is often encountered by …

Precision Measurement Of The Lambda_B Baryon Lifetime, Bilas Kanti Pal

Dissertations - ALL

The ratio of the Lambda_b baryon lifetime to that of the B0 meson is measured using data corresponding to an integrated luminosity of 3.0 /fb collected with the LHCb detector using pp collisions at the LHC. The Lambda_b baryon is observed in the decay mode Lambda_b ->J/psi p K-, while the B0 meson decay used is the well known B0->J/psi pi+ K- mode, where the pi+K- mass is consistent with that of the K*0(892) meson. The ratio of lifetimes is measured to be 0.971+/-0.007+/-0.005, in agreement with theoretical expectations based on the heavy quark expansion. Using previous determinations …

Dissertations - ALL

This dissertation will explore the analysis of waveguide discontinuities for the purpose of dielectric filled waveguide filter analysis and design. The filling media studied are uniaxial media and uniaxial media embedded with metamaterial. A literary search provides numerous methods and numerical techniques for analyzing waveguide class problems, but ultimately the Mode Matching Method (MMM) is chosen as the numerical analysis technique for this dissertation.

An overview of waveguide theory and its application to the Mode Matching Method are presented. The Mode Matching Method is then used to analyze simple cases to confirm the numerical accuracy. Once accuracy is confirmed, Mode …

Retrieval Of Free Space Radiation Patterns Through Measured Data In A Non-Anechoic Environment, Weixin Zhao

Dissertations - ALL

Antenna pattern measurements are usually carried out in an anechoic chamber. However, a good anechoic chamber is very expensive to construct. Previous research has attempted to compensate for the effects of extraneous fields measured in a non-anechoic environment to obtain a free space pattern that would be measured in an anechoic chamber. Existing compensation techniques are like the Test Zone Field compensation method, the Fast-Fourier-Transform-based method, the Matrix Pencil method, and the Antenna Pattern Comparison technique.

This work illustrates and extends a deconvolution methodology which allows the antenna measurement under a non-anechoic test environment and retrieves the free space radiation …

Experimental Investigation Of The Active Flow Control On A Two-Dimensional Wind Turbine Airfoil, Guannan Wang

Dissertations - ALL

Wind turbine blades experience unsteady aerodynamic loading under various off-design conditions. The fatigue loading reduces the operational time of the wind turbine hence leads to an increase in the Cost of Energy (CoE) of the wind power. In this study, active flow control with unsteady blowing actuators was applied to a two-dimensional wind turbine airfoil to alleviate the unsteady aerodynamic loading and improve the aerodynamic performance, particularly under large scale freestream disturbances. A low speed, open jet aeroacoustic wind tunnel was designed and constructed based on an existing anechoic chamber for this investigation. A theoretical analysis based on a Blade …

Recombinant Expression, Purification, And Characterization Of An Hiv-1 Tat-Human Cyclin T1 Chimera, Collin Lesley Fischer

Dissertations - ALL

Efficient transcription of the human immunodeficiency virus type 1 (HIV-1) requires the interaction of the viral protein Tat with the trans-activation response (TAR) stem-loop of the long-terminal repeat (LTR) portion of nascent viral RNA. The production of viable transcripts is enhanced dramatically by the interaction of HIV-1 Tat with the host protein human Cyclin T1. Interaction with hCycT1 remodels Tat protein contributing a single cysteine residue that is critical to the formation of the second of two zinc fingers (Zn2). Here we suggest that it is the presence of this critical cysteine residue and not the presence of arginine residues …

Barriers To Membership In The American Dental Hygienists’ Association In The State Of Georgia, Brandy Henderson

Electronic Theses and Dissertations

Professional associations must have a significant level of membership to be effective. Georgia membership is increasingly low; therefore, ADHA cannot represent dental hygienists’ interests. This study determined factors that caused dental hygienists to continue to forgo membership in the ADHA. Several theoretical views of professional membership were considered. The sample was acquired from an unbiased systematic sampling of 50% (3,270) of registered dental hygienists and a convenience sampling of ADHA nonmembers at 2 continuing education seminars in Georgia. Data collection procedures included an electronic cover letter, consent form, and survey via Survey Monkey or hard copies for seminars. Three hundred …

Comparing Resiliency In Early And Late-Life Bereavement., Janna Lynn Imel

College of Arts & Sciences Senior Theses

Bereavement is the state of dealing with a significant loss (M.S. Stroebe, Hansson, Schut, & Stroebe, 2008). Although evidence suggests that there are differences in the bereavement and coping styles of older and younger adults, few studies have been done focusing solely on the differences. The lack of research on this topic merits further study. The purpose of this project was to examine the differences in negative emotions, affective complexity, and repressive coping, between bereaved younger and older adults. We hypothesized that bereaved older adults would report fewer negative emotions, have greater emotional complexity, and use repressive coping more than …

Symptoms In Early And Long-Term Breast Cancer Survivors Who Have Completed Primary Therapy, Faith Strunk

Dissertations and Theses (Open Access)

Background

Many breast cancer survivors continue to have single or multiple symptoms after they have completed primary cancer therapy. The quantifiable, subjective experience of multiple symptoms and their impact is defined as symptom burden. Previous research has focused on symptoms during primary therapy or shortly after completion of treatment.

Objectives

Our study objectives were to determine whether symptom burden differed according to survivor status (early as opposed to long-term survival) and/or use of endocrine or hormonal adjuvant therapy. We hypothesized that there would be no difference in the symptoms expressed among early- and long-term survivors.

Methods

In this cross-sectional study, …
